Welcome to the bottom of Fall Creek, a popular destination for the
local canyoneers. Fall creek offers many cool swimming holes &
beautiful falls but this is the only one you can reach without
climbing gear.
Right after I pulled into the parking area (N34 17.842 W118
10.188) a carload of canyoneers piled out with all their gear. We
chatted a bit & discussed our plans; they were going up the the
top of these falls to rappel down while I would be taking my bike
to the bottom of Big Tujunga Cyn. and hiking from there.
The bike thing wasn't that great of an idea. The road down is
very rocky, with lots of hairpin turns so my speed was kept down. I
think it only probably saved me about a half hour tops.
To find the cache: If you face the falls and turn to your left,
there's a tree up the slope behind you. Look behind it.
Hint:

It might be more fun to backpack down here & camp at the
Fall Creek Trail camp and make a week end out of it. I intend to
try that this summer.
